High-flow bistable solenoid valve with dual coil redundancy, featuring manual override and position-indication LEDs. The aluminum alloy body with hard anodized coating resists chemical corrosion and mechanical wear. Designed for continuous duty cycles up to 1 million operations with ≤5μm filtered air (ISO 8573-1 class 3).
- Automated assembly line clamping systems
- Textile machinery cylinder control
- Plastic injection molding ejectors
- Semiconductor wafer handling robots
- Beverage filling station actuators
Installation note:
Mount in vibration-free environments using M4 mounting screws (not included).
Maintain 15mm clearance below valve for manifold heat dissipation.
Use copper-free anti-seize compound on threads in humid environments.
Maintenance alert:
Replace internal filters every 2,000 operating hours in high-particulate environments.
Never lubricate - pre-lubricated air supply required.
